2021-2022 Audi Sunroof Frame Modification TSB

Audi has released Technical Service Bulletin (TSB) 2065731/4, dated July 17, 2024, to address a condition affecting the sunroof assembly in certain 2021-2022 Audi Q3, Q8, e-tron, e-tron Sportback, RS Q8, and SQ8 models. This bulletin supersedes an earlier version, TSB 23-65, dated April 7, 2023, and provides updated information regarding the sunroof frame modification.

This TSB specifically addresses customer complaints related to the front sunroof glass panel or sunroof frame. If these components require replacement, an interference issue may arise, necessitating a modification to the sunroof frame to ensure proper functionality. Owners searching for "Audi e-tron sunroof frame modification" will find this information relevant.

Symptoms of Sunroof Interference

Owners may experience various complaints if the front sunroof glass panel or sunroof frame needs replacement. The primary symptom is an interference between the sunroof frame and the front sunroof glass panel. This interference is caused by a protruding water guidance washer on the sunroof mechanism pivot. As a result, the rubber "skirt" on the front glass panel also protrudes, which can prevent the front glass panel from completing its closing sequence.

Technical Background

The design and development of the sunroof assembly have evolved. This progression means that when replacement sunroof frames and front sunroof glass panels are installed, they may require a specific modification to ensure compatibility with the existing assembly. This ensures that the sunroof operates smoothly and without obstruction.

Repair Procedure Summary

If a vehicle requires a replacement of the sunroof frame or front sunroof glass panel, and the interference condition is present, a modification procedure is necessary. The process involves removing the front sunroof glass panel. Technicians then use a small pair of diagonal cutters (also known as side cutters, as shown in Figure 4 of the TSB) to trim the water guidance washer. This trimming ensures the washer no longer protrudes past the pivot pin, resolving the interference. This operation must be performed on both sides of the sunroof mechanism. After modification, the front sunroof glass panel is reinstalled and adjusted according to specifications found in ElsaPro. Finally, the sunroof panel and rollershade end stop adaptation must be set using the appropriate switches.

Important Warnings During Repair

Audi emphasizes specific precautions during the sunroof frame modification process:

• "NOTICE: During the modification procedure exercise extreme caution not to scratch or otherwise damage the surrounding metal components of the sunroof frame and lifting mechanism. Surround the area being modified with masking tape if necessary."
• "NOTICE: Ensure that all plastic fragments from the water guidance washer created during the modification are removed completely. Use a vacuum cleaner if necessary. Stray plastic fragments from this modification that remain will cause permanent damage to the sunroof frame mechanism."
